Substrate, fabrication method thereof and a display using the same

Abstract

A substrate board, a fabricating method thereof, and a display using the same are provided. The substrate board includes a substrate having at least a rigid area and at least a flexible area, and at least an electronic component disposed on a surface of the substrate, wherein the rigid area is thicker than the flexible area. A patterned high-extensive material may be additionally disposed on the substrate to improve reliability thereof. The rigid area and the flexible area may be formed by molds or cutters. By using an above structure, the electronic component is less affected when the substrate is under stress, so that good characteristics are maintained.

1. A substrate board, comprising:
 a substrate having a first surface and a second surface opposing to the first surface and, comprising a plurality of rigid areas and a plurality of flexible areas, wherein each of the rigid areas is thicker than each of the flexible areas; and the substrate further has a plurality of recesses entirely distributed on the second surface so as to define the rigid areas and the flexible areas; 
 at least an electronic component, disposed on and entirely covering the first surface; and 
 a patterned high-extensive material layer disposed on and entirely covering the second surface, wherein the recesses are filled with the patterned high-extensive material layer. 
 
     
     
       2. The substrate board as claimed in  claim 1 , wherein each of the rigid areas is at least twice the thicker than each of the flexible areas. 
     
     
       3. The substrate board as claimed in  claim 1 , wherein the electronic component comprises at least a pixel area and at least a lead area, the pixel area is disposed on the rigid area, and the lead area is disposed on the flexible area. 
     
     
       4. The substrate board as claimed in  claim 1 , wherein the electronic component comprises at least a pixel area and at least a lead area, and each pixel area comprises a device area and a display area, wherein a part of the device area is disposed on the rigid area, and a part of the display area is disposed on the flexible area. 
     
     
       5. The substrate board as claimed in  claim 4 , wherein the pixel areas are arranged in alignment or in interlace. 
     
     
       6. The substrate board as claimed in  claim 1 , wherein the electronic component comprises at least a pixel area and at least a lead area, and each pixel area comprises a device area and a display area, wherein a part of the device area is disposed on the flexible area, and a part of the display area is disposed on the rigid area. 
     
     
       7. The substrate as claimed in  claim 6 , wherein the pixel areas are arranged in alignment or in interlace. 
     
     
       8. A display device, comprising:
 a plurality of pixel areas and a plurality of lead areas, wherein the lead areas are connected to the corresponding pixel areas according to configurations thereof, and are connected to an external signal source for transmitting signals to the corresponding pixel areas to display images; and 
 a substrate having a first surface and a second surface opposing to the first surface, wherein the pixel areas and the lead areas are disposed on and entirely covering the first surface according to a layout, the substrate comprises a plurality of rigid areas and a plurality of flexible areas, and each of the rigid areas is thicker than each of the flexible areas, and the pixel areas are disposed in the rigid areas, and the lead areas are disposed in the flexible areas respectively, and the substrate further has a plurality of recesses entirely distributed on the second surface to define the rigid areas and the flexible areas; and 
 a patterned high-extensive material layer disposed on and entirely covering the second surface, wherein the recesses are filled with the patterned high-extensive material layer. 
 
     
     
       9. The display device as claimed in  claim 8 , wherein the pixel areas are arranged in alignment or in interlace.
